Multiplier-free carrier-phase recovery for real-time receivers using processing in polar coordinates
A low-complexity, multi-format carrier-phase estimation algorithm for QPSK and 16QAM is demonstrated. Our multiplier-free hardware implementation is enabled by operating in polar coordinates and allows for detection of QPSK signals beyond 38 GBd.
